This chapter is a continuation of Chapter 10 and devoted to discuss the
waveguides of a circular cross-section. The general formulations for the metallic
waveguides that are presented in Chapter 10, will be applied in this chapter to analyze
the behavior of electromagnetic waves and power flow in the metallic waveguide of
circular cross-section. The topics of the chapter are analyzed in details and supported by
numerous illustrative examples and figures in addition to solved problems. Homework
problems are included at the end of the chapter.
Keywords: Attenuation constant, cut-off frequency, cut-off wavelength,
dominant mode, group velocity, phase constant, phase velocity, power loss,
Poynting vector, propagation constant, wave impedance.
